China-based Eternal Material Technology (EMT) announced that it has started to construct its 15-tons OLED material production facility in Hefei. Yesterday the company held a groundbreaking ceremony at the construction site. EMT company expects the plant to begin mass producing materials in the second half of 2021. The planned total investment of the project (which will also include production of other materials) is 500 million yuan (or around $72 million USD).

EMT says that it has been able to achieve design wins for its ETL materials, and also other OLED related materials - and has already achieved sales of over 230 million Yuan ($33 million USD). EMT offers over 20 different OLED materials.

Poland-based TADF developer Noctiluca reports that the company continues to improve its emitter platform, and the company recently concluded testing a new family of emitters that have revealed great TADF properties, good to excellent QY and blue emission. Noctiluca released the raw data (available from company under the NDA) that details the performance of several new blue emitters. Here is a link to the summary of these results.

Noctiluca’s Team have a history of making custom high purity compounds to specific needs, and its TADF compound family has a high level of customization which will allow the company to tailor its materials for specific OLED stacks. In fact the company's next step is to work with industry leaders and OLED material developers to test its materials within commercial-grade OLED stack architectures to continue its development work and enhance the performance of its OLED emitters.

Researchers from Korea's Pusan National University have developed an efficient deep-blue phosphorescent OLED emitter. The researcher say that their new materials has an EQE of 24% while the color point is CIE (0.149, 0.085).

According to the Korean press, the main achievement in this research was the adjustment of the doping concentration of a novel dopant (mer ‐Ir1) to optimize the balance of electron and holes in the light emitting layer.

OLED material developer Cynora announced its first commercial product, a fluorescent blue emitter that is based on an "advanced molecular design" that is 15% more efficient that current fluorescent blue emitters on the market. Cynora brands its new material as cyBlueBooster, and it says it is currently available for commercialization in several shades of blue.

This could be very exciting news - while the whole industry is looking for next-generation emitters using TADF or PHOLED technologies, Cynora could have found an easier path to reduce power consumption by 15%. OF course a TADF or PHOLED emitter will achieve a reduction of 75% in power consumption compared to currently-used fluorescent emitters.
